Description

Telescopic box support

Technical Field

The present disclosure generally relates to telescoping support stands, cassette holders, catheter support stands, and floor support stands.

Background

The present disclosure relates to support brackets, and in particular to support brackets for supporting electrical boxes and related devices. Typically, electrical or communication devices are installed in buildings using mounting brackets. The electrical or communication device is connected to the mounting bracket and, in turn, secures the mounting bracket to a frame (e.g., a wall stud) of the building. In some cases, junction boxes are used to house and protect electrical and communication devices, such as power outlets, electrical switches, associated electrical wiring, communication terminals (e.g., terminals for optical fibers), and associated communication cables (e.g., fiber optic cables). The junction box is secured to the mounting bracket such that the electrical or communication device is in turn secured to the mounting bracket.

There is a need in the art for a support bracket that allows attachment of devices at various locations, easy attachment to wall studs, control of spacing from the floor, and ease of assembly and low cost. The present invention seeks to address these needs.

Detailed Description

In general, the support bracket described herein is used to attach a mounting bracket to a stud of a junction box to a wall. Each support frame is configured to support cartridge holders of various sizes and in various orientations. Each support bracket can also be temporarily attached to the upright without the use of fasteners. In this way, an operator, such as a construction worker, does not have to hold the support bracket in place on the upright before securing the support bracket to the upright, and thus the support bracket can be permanently secured to the upright without the need for hands and/or without the use of additional tools to hold the support bracket in place.

Referring to fig. 1, a retractable support stand is indicated generally at reference numeral 100. The support stand 100 generally has an adjustable length L. The support stand 100 generally includes nested first and

second telescoping members

102 and 104, respectively. The length L of the stent 100 can be adjusted by relative movement of the two

telescoping members

102, 104. Specifically, by sliding the

telescoping members

102, 104 inward, the length L is reduced. Conversely, by sliding the

telescoping members

102, 104 outward, the length L is increased. Thus, the bracket 100 can be made to fit various distances between adjacent uprights S. The

telescoping members

102, 104 have indicia 106 printed, etched, or otherwise provided thereon to indicate the particular length L of the stent 100 in a given configuration. Each

telescoping member

102, 104 includes upper and lower legs and a post connecting arm 110 connected to the legs. In the illustrated embodiment, the

members

102, 104 are identical and cooperate with one another such that, for example, the upper leg of a first telescoping member is positioned forward of the upper leg of a second telescoping member and the lower leg of the first telescoping member is positioned rearward of the lower leg of the second telescoping member. Mounting holes 112 are positioned on either side (e.g., top and bottom) of the post connecting arm 110.

In one embodiment, each of the post connecting arms 110 has a main body (e.g., a top portion in fig. 1) that spans the width of the post to which it is connected. The opposing portion (e.g., the bottom portion in fig. 1) of the post connecting arm 110 does not protrude across the post except for the tabs that define the mounting holes 112. Thus, once flipped and combined, a bracket 100 can be used alongside another bracket 100 without interfering with the mounting holes 112 and the mounting holes of subsequent brackets. In various embodiments, to assist a user in installing the brace 100, the post connecting arm 110 may have an marked centerline 116.

The body of the stud connection arm 110 may also include a clamping flange 118 configured to engage a stud of a wall. Each clamping flange 118 is resiliently deflectable and is configured to apply a force to the post to retain the bracket 100 on the post when the bracket 100 is mounted on the post. The inner portion of the post connecting arm 110 may include a flange 120 that protrudes rearward to add rigidity and stability to the brace 100, for example.

In various embodiments, the length L of the bracket 100 may be used during installation of the bracket 100 to assist a user in installing the bracket 100 at an appropriate height on the standard S. As best depicted in fig. 18, the telescoping arm 104 may include markings 122 that indicate the particular height at which the bracket 100 is to be installed when the rightmost upright connecting arm 110 is placed over the bottom beam. It should be understood that any reference to top, bottom, right, left or any other term with respect to the relative positions of reference components and structures is described with respect to the orientation of a bracket mounted in a column-to-column configuration. As shown in fig. 19A and 19B, the

telescoping arms

102, 104 can include stops 126 (e.g., two stops; stop lances) that inhibit further collapse of the stent 100 beyond its minimum length (e.g., 18 inches). The bracket 100 is placed substantially parallel to the upright S with the rightmost upright coupling arm 110 resting on top of the bottom beam. The fastener is placed in the leftmost tab that defines the mounting hole 112 (see fig. 16A and 17A). The right end of the stand 100 is then pivoted upward (see fig. 16B and 17B). Once the bracket 100 is generally perpendicular to the post S, the left-most clamping flange 118 may be engaged to help hold the bracket 100 in this position. As shown in fig. 20A-20D, the engagement of the clamping flange 118 and the mast connection arm 110 on the mast S helps to mount the bracket 100 in a generally horizontal position, i.e., generally perpendicular to the mast S. The length L of the stand 100 can then be adjusted as desired by sliding the

telescoping arms

102, 104. As shown in fig. 16C, the length L of the support 100 may need to be increased, in which case the

telescoping arms

102, 104 would be slid apart. As shown in fig. 17C, the length L of the support 100 may need to be reduced, in which case the

telescoping arms

102, 104 will slide together. Once the proper length L is achieved, the rightmost clamping flange 118 may be engaged to further assist in holding the stent 100 in that position. The remaining fasteners can then be installed in the mounting holes 112 (see fig. 16D and 17D).

Each of the

telescoping members

102, 104 includes a plurality of holes along its length. Each of these holes allows for the attachment of various accessories and devices. As depicted in fig. 2, these holes may allow for connection of the cartridge holder 200. The cartridge holder 200 includes a hole that allows access to the holder 100 to allow the cartridge holder 200 to be secured thereto by a slot 202. The cartridge holder 200 may include a first cartridge mounting opening type 204a and a second cartridge mounting opening type 204 b. The cartridge holder 200 contains two of each of the first cartridge mounting opening type 204a and the second cartridge mounting opening type 204 b. In the illustrated embodiment, the upper two cartridge mounting opening groups are the first cartridge mounting opening type 204a and the lower two cartridge mounting opening groups are the second cartridge mounting opening type 204b, but other locations of the first and second cartridge mounting opening types are within the scope of the present disclosure. The first and second

mounting opening types

204a, 204b are configured to receive fasteners in a plurality of different positions to enable different sizes of junction boxes J to be attached to the box bracket 200 and in different orientations (fig. 4).

Each cartridge holder 200 can also include one or more plaster ring mounting tabs 206 for attaching a plaster ring PR (e.g., a mud cake ring) (fig. 3) to the cartridge holder 200 without the use of a junction box J. Further details of the gypsum ring mounting tabs 206 and how they will be used to attach the gypsum ring PR can be found in U.S. patent No. 9,444,236. The plaster ring mounting tab 206 can also include a fastener opening therein. Thus, the cartridge holder 200 may be adapted for use with pre-manufacturing systems. Fasteners can be inserted into fastener openings in the plaster ring mounting tabs 206 and can be used to secure the mounting box 200 to the support bracket 100.

The cartridge holder 200 also includes a pair of left and right upright mounting

flanges

208, 210. Left and right

stud mounting flanges

208, 210 extend laterally outward from the left and right edges of the panel, respectively. Typically, these

stud mounting flanges

208, 210 are used to secure the cartridge holder 200 to a stud of a wall (fig. 5). The

column mounting flanges

208, 210 are substantially planar and are configured to engage side surfaces of the column. The

post mounting flanges

208, 210 are coplanar with one another and generally parallel to the panel of the cartridge holder 200. The

stud mounting flanges

208, 210 define fastener openings 212 to receive fasteners (e.g., self-tapping sheet metal screws) (fig. 5) for securing the cartridge holder 200 to the studs. Fastener openings 212 are also provided on the left and right upright mounting

flanges

208, 210 such that corresponding fastener openings 212 of two cassette holders 200 arranged in an overlapping side-by-side arrangement are aligned with each other and can receive fasteners therein (fig. 6).

The cartridge holder 200 may also include a base flange 216 extending rearwardly from the lower edge of the panel. The base flange 216 is substantially perpendicular to the panel. In a preferred embodiment, the base flange 216 extends from the panel a distance equal to the depth of the stud (e.g., stud wall) such that the rearmost edge of the base flange 216 engages the interior of the opposite face of the wall (e.g., dry wall) to provide additional support for the cassette holder 200 when secured to the stud or telescoping support stand.

The top and/or bottom of the cartridge holder 200 may also include at least one clamping flange 220 configured to engage the telescoping members of the support stand 100. Each clamping flange 220 is resiliently deflectable and is configured to apply a force to the cradle 100 to retain the cartridge cradle 200 on the cradle 100 when the cartridge 200 is mounted on the cradle 100.

The cartridge holder 200 also contains a strap 224 (e.g., formed by a punch-cut) that extends forward away from the cartridge holder 200 to allow attachment of additional accessories, such as, for example, a catheter support stand 300 (fig. 7).

Referring now to fig. 7 and 8, the catheter holder 300 includes tabs 302 that mate with the bands 224 of the cartridge holder 200 to allow the catheter holder 300 to be attached to the cartridge holder 200. Extending outwardly from each tab 302 is a connecting flange 304. The connection flange 304 includes fastener openings 306 that correspond to the fastener openings 202 of the cartridge holder 200 to allow connection of each of the catheter holder 300 and the cartridge holder 200 to the holder 100. The connection flange 304 may also include a rearward facing flange 310 to provide a secondary connection point to the support bracket 100 (fig. 9). The rearward facing flange 310 clamps around the

telescoping members

102, 104 of the support stand 100 to provide additional support.

Extending upwardly and rearwardly (e.g., at a rearward facing angle) from the connecting flange 304 at its outer edge is an arm 308. The arms 308 are made of a deformable material that can be manipulated by a user to allow the catheter to be connected in place. The support flange 312 is generally parallel to the connection flange 304 and at the opposite end of the arm 308. The support flange 312 contains openings of various sizes and shapes to allow for many types and locations of clamps (see fig. 10A-10D). As shown in fig. 10A, the support flange 312 may include a resiliently deflectable strap 316 to capture and support the catheter between the support flange 312 and the strap 316. When the strap 316 is not needed, it may remain in the down and disengaged position, as shown in fig. 10B-10D.

The tabs 302 define a space 314 extending therebetween. The space 314 allows the catheter holder 300 to be installed around existing catheters without requiring removal or replacement of the catheter.

A floor support bracket 400 is also provided herein (fig. 11 and 12). The floor support stand 400, like the catheter support stand 300, includes tabs 402 that mate with the straps 224 of the cassette holder 200 to allow the floor support stand 400 to be connected to the cassette holder 200. The floor support bracket 400 also includes an attachment flange 404 extending outwardly from each tab 402. The attachment flange 404 includes fastener openings 406 that correspond to the fastener openings 202 of the cassette holder 200 to allow each of the backplane holder 400 and the cassette holder 200 to be attached to the holder 100, if desired. The connection flange 404 may also include a rearward facing flange 406 (fig. 12) to a secondary connection point of the support stand 100. The rearward facing flange 406 clamps around the telescoping members of the support stand 100 to allow additional support. Extending downwardly and in a planar fashion from each attachment flange 404 is an arm 408. The arm 408 terminates in a bottom flange 410 that is substantially parallel to the connecting flange 404. The bottom flange 410 may include a tab 412 having a fastener opening 414 that allows a fastener to be attached to the sill. The tab 412 may be placed over the sill (i.e., the bottom flange 410 on one side of the sill and the tab 412 on the opposite side of the sill) and the fastener secured to the sill (fig. 13).

The skilled person will appreciate that the support stand 100, the cartridge holder 200, the catheter support stand 300 and the floor support stand 400 may be combined in a variety of ways. By way of example, in the embodiment shown in fig. 13, the floor support 400 is combined with the cassette holder 200. In the embodiment shown in fig. 14, the floor support is combined with the cartridge holder 200 and the catheter support 300. In the embodiment shown in fig. 15, the support 100 is combined with a cassette holder 200, which in turn is connected to a catheter support 300 and a floor support 400.
